Hi.

I'm looking for a Robin Hood with a 2L Pinto engine. Approximately, what would the BHP be if fitted with  Weber carbs?

 

Are there any people in Hampshire that specialise in servicing/tuning/repairing this sort of car?

 

Replies will be appreciated.

 

Thanks. Mick.

The Pinto comes with 110 or 115 injected
The injection head is better than a non injection head

The head makes the power adding a good cam can add a bit more then induction, carbs or injection.
Just slapping a pair of Weber 40's on a standard head will not make a huge difference.

Having a good head well prepared with larger valves, properly ported then better carburation can add that little bit more.
The standard 32/36 Weber is good for 130bhp
The 38 DGAS carb can push 150bhp
More than 150bhp and you want 45DCOE Weber's

This is a very simplistic description

depending on how old the pinto is you might benefit from fitting electronic ignition. The old ones would be points. Mine is a later 1991 and had electronic as standard but you can buy an aftermarket setup. Having a fully mappable system would be the best but that costs to have it setup on a RR. 

 

I'd look for an old independent garage with an old chap still working there as they will no doubt have worked on these in the past. These are old simple engines and a spanner or two will do most jobs.

 

If the car is ~750kg and 105bhp that is still 140bhp/tonne. Enough to be spritely in a little car.

Im assuming you have webbers on it. If its got a standard cam youll not be getting much over standard. A standard head with 40dcoe/dhla and an uprated cam along with a tubular manifold, ie a basic kitcar install, would be a bit more, but very much dependant on condition of engine.

Im only down road in Gosport and can set up carbs. Best for you would be to give slark a call in Amesbury. Just of 303 at Solstice services. Great guy and im a very happy customer but mine was an Emerald RR session.

Twin 40's, a 285 cam and a little amateur clean up of the ports (standard valves) got me 118bhp at the wheels. (A good 130bhp at the flywheel). As snapper said thats lots in a seven type car.

We are just a few miles away at West Tytherley, welcome to pop over sometime; although you won't learn a great deal on "go faster"  mods.  Florin only has 80 bhp at the wheels but is still quick enough to get me into trouble.

Hi. I received several replies to my Post and all were useful and informative. I have replied but my replies are not showing on the Forum (Can anyone explain why?) So, this is the only way I could think of to say thanks to all that replied. From the replies I have decided that I don't need anything highly tuned. I will go for carburetors because I have reasonable experience of Motorbikes and cars with carbs. Fuel Injection means an ECU and sensors and I'm not into that. To "Florian" - I would like to take you up on your offer to visit. My phone No is 01489 895412. I'm retired so very flexible with time. Cheers. Mick.

If you search some of my posts, i replied to another poster with a base set of jets etc that will work very well as a basic setup for most 2ltr 4 pots.
To set up the spindles has also been posted by me at another time.
On a pinto the ignition setup is considered paramount. You dont need anything fancy, just a well set up electrionic system will do the trick.
If yours is a standard 2ltr then a good cheap upgrade is the cam from the 2ltr injection as it works very well.
The closest you can get to a tuned exhaust manifold the better. The extraction of gasses will do more for you than you would think.

I would also guess that having a straight through exhaust would help a bit too, but i could be wrong as there are various other factors such as back pressure to take into consideration and it all starts to get a bit technical especially when you start taking into account 4-1 or 4-2-1 manifolds and primary tube lengths and the like. 

 

Depends on budget as i am sure Snapperpaul will tell you it ain't cheap once you start pushing the limits.

 

At the end of the day though i have a 1.6 pinto without much done to it, only a 2ltr cam, 4-1 tubular manifold to straight through exhaust and that still gives me a huge smile and moves pretty well. I was stuck behind a few slow cars today on the way home along the edge of the river wye and it just didn't matter. Sun was creeping out and it was awesome to hear the burble of the engine and get to enjoy the scenery, it's not always about screaming 0-60 times ;)

Slight highjack of this thread but it was so nice to hear that someone else is happy with their 1.6! Mine too has the 2ltr cam.
I did recently add a small 10" extra exhaust box. I wasn't happy with the sound before. Loud and tractor like! Much nicer sound now and I believe it pulls a bit better. That might be my imagination though.
